This patch introduces a /proc filesystem interface to ksmbd, providing visibility into the internal state of the SMB server. This allows administrators and developers to monitor active connections, user sessions, and opened files in real-time without relying on external tools or heavy debugging. Key changes include: - Connection Monitoring (/proc/fs/ksmbd/clients): Displays a list of active network connections, including client IP addresses, SMB dialects, credits, and last active timestamps. - Session Management (/proc/fs/ksmbd/sessions/): Adds a global sessions file to list all authenticated users and their session IDs. - Creates individual session entries (e.g., /proc/fs/ksmbd/sessions/<id>) detailing capabilities (DFS, Multi-channel, etc.), signing/encryption algorithms, and connected tree shares. - File Tracking (/proc/fs/ksmbd/files): Shows all currently opened files across the server, including tree IDs, process IDs (PID), access modes (daccess/saccess), and oplock/lease states. - Statistics & Counters: Implements internal counters for global server metrics, such as the number of tree connections, total sessions, and processed read/write bytes.
